In one embodiment, egress provider edge devices (PEs) send advertisements to ingress PEs for address prefixes of a first multi-homed customer network that desires path diversity through a service provider network to a second customer network. A first ingress PE receives the advertisements, and determines whether a second ingress PE is multi-homed with the first ingress PE to the second customer network. If so, the first ingress PE computes a plurality of diverse paths within the service provider network from the first and second multi-homed ingress PEs to a corresponding egress PE. If a plurality of diverse paths exists, the first ingress PE employs one of those paths to establish a first tunnel from itself to a first egress PE, and the second ingress PE employs another of the paths to establish a second tunnel from itself to a second egress PE that is diverse from the first tunnel.
